Want your iPhone battery to last longer, both through the day and over its total lifespan? These 10 proven tips will help you maximize battery performance based on how lithium-ion batteries actually work.
Daily Battery Life Tips
These tips help your battery last longer each day:
Enable Focus modes to automatically reduce notifications and save battery during work, sleep, or exercise. Go to Settings > Focus to set them up.
1. Enable Low Power Mode Strategically
Low Power Mode reduces background activity and visual effects. Enable it when:
- Battery drops below 20%
- You need your phone to last longer
- You are traveling without a charger
How: Settings > Battery > Low Power Mode, or ask Siri
2. Manage Screen Brightness
The display is your iPhone's biggest battery consumer. To optimize:
- Enable Auto-Brightness (Settings > Accessibility > Display > Auto-Brightness)
- Use Dark Mode on OLED iPhones for significant savings
- Reduce brightness manually when possible
3. Control Background App Refresh
Apps refreshing in the background drain battery. Manage them:
- Settings > General > Background App Refresh
- Disable for apps that do not need real-time updates
- Keep enabled for messaging, email, and navigation apps
4. Optimize Location Services
GPS is power-hungry. Review your settings:
- Settings > Privacy & Security > Location Services
- Set apps to "While Using" instead of "Always"
- Disable location for apps that do not need it
5. Reduce Push Email
Constant email checking drains battery:
- Settings > Mail > Accounts > Fetch New Data
- Change from Push to Fetch every 15-30 minutes
- Or set to Manual for maximum savings
Long-Term Battery Health Tips
These tips extend your battery's total lifespan:
6. Enable Optimized Battery Charging
This feature learns your charging routine and waits to charge past 80% until you need your phone:
- Settings > Battery > Battery Health > Optimized Battery Charging
- Reduces time spent at 100%, which stresses the battery
- Works best with consistent daily routines
7. Avoid Extreme Temperatures
Heat is the enemy of battery longevity:
- Do not leave iPhone in hot cars (can exceed 60°C / 140°F)
- Avoid direct sunlight during use
- Remove case while charging if phone gets warm
- Ideal operating range: 16-22°C (62-72°F)
8. Use Quality Chargers
Cheap chargers can damage your battery:
- Use Apple-certified (MFi) chargers and cables
- Quality chargers provide stable voltage
- Avoid unknown brands from discount stores
9. Follow the 20-80 Rule When Possible
Keeping your battery between 20% and 80% reduces wear:
- Charge before dropping below 20%
- Unplug when reaching 80% if convenient
- Occasional full charges are fine for calibration
10. Reduce Fast Charging Usage
Fast charging generates heat, which accelerates degradation:
- Use standard 5W-20W chargers overnight
- Save fast charging for when you actually need it
- Wireless charging is gentler than fast wired charging
